As can be seen from the aforementioned studies and references, many illegal aliens are not your casual immigration violating, ID theft committing, law breaker. Many are recidivists – a.k.a. career criminals, like Juan Leonardo Quintero, who was deported after being convicted of indecency with a child, but who later came back and then just recently killed a Houston cop in cold blood, leaving a widow and five now fatherless children.

Many of the brutal crimes referenced in the two previous sections are gang related with the growing Mara Salvatrucha (MS-13) gang being notoriously brutal in carrying out its criminal activities. How much is unknown because NOBODY IS TRACKING IT.

If you do not yet have any of the violent illegal alien gangs in your area, you might want to take note of US Undocumented Settling in New Areas where it noted that illegal aliens are moving away from traditional illegal immigrant enclaves and settling in mass in newer areas and a fairly recent Washington Times article, Gang follows illegal aliens, that noted:

"The violent MS-13 - or Mara Salvatrucha - street gang is following the migratory routes of illegal aliens across the country, FBI officials say, calling the Salvadoran gang the new American mafia.

MS-13, has a significant presence in the Washington area, and other gangs are spreading into small towns and suburbs by following illegal aliens seeking work in places such as Providence, R.I., and the Carolinas, FBI task force director Robert Clifford said. "The migrant moves and the gang follows," said Mr. Clifford, director of the agency's MS-13 National Gang Task Force."

As reported by Known Gangs, one of the nation's leading private organizations specializing in gangs training and information, here is some information on one of the most violent gangs that has a very high illegal alien involvement, the Mara Salvatrucha (MS-13):

In the 1980s, "A group of Salvadorian immigrants created a new gang calling themselves Mara Salvatrucha also known as MS-13. It is believed they got their name from combining the name of "La Mara," a violent street gang in El Salvador with Salvatruchas, a term used to denote members of the Farabundo Marti National Liberation Front. This was a group of Salvadorian peasants trained as guerilla fighters. The "13" was added to pay homage to the California prison gang, the Mexican Mafia.

Members of this newly formed gang soon engaged in violent criminal acts. They quickly became known as one of the most violent gangs in the area because many of their founding members had experience or training in guerilla warfare, thus gaining a level of sophistication that superseded their rivals.

Mara Salvatrucha has become Central America's greatest problem. In addition to violent acts committed by the gang against citizens and gang rivalries, the gang has even engaged in organized violent acts against the government. In 1997 the son of Honduras President Ricardo Maduro was kidnapped and murdered by MS-13 members. MS-13 members have continued to taunt Central American government officials. Members also left a dismembered corpse with a note for the Honduras president that "more people will die ... the next victims will be police and journalists." In 2004, Guatemalan President Oscar Berger received a similar messages attached to the body of a dismembered man from MS-13 members.

In 2002 in the city of Tegucigalpa in the Honduras, MS-13 members boarded a public bus and immediately executed 28 people including 7 small children. Again, they left a message written on the front of the bus taunting government officials.

... Currently El Salvador has a murder rate of approximately 54 per every 100,000 people, while the United States murder rate is approximately 6 per every 100,000.

... MS-13 members in our country are known to be involved in all aspects of criminal activity. Some law enforcement sources have reported that because of their ties to their former homeland, MS-13 members have access to sophisticated weapons thus making firearms trafficking one of their many criminal enterprises.

Despite their access to weaponry, there have been many high-profile murders and assaults in which MS-13 have used machetes to attack their victims.

The federal government has increased efforts to locate and deport illegal MS-13 members living in our nation but with the lack of cooperation from many cities whom support sanctuaries policies, has made the government's job an uphill battle."

As noted in Gangs Or Us, "Since there are no "precise" statistics, it is difficult to estimate the number of cliques or the number of members. It has been estimated that MS-13 has over 15,000 members and associates in at least 115 different cliques in 33 states, and these numbers are continually increasing."

"A 17-year-old Honduran citizen and MS-13 gang member convicted as an adult for participating in the sexual assault of two teenage girls in Maryland was deported today by U.S. Immigration and Customs Enforcement (ICE).

Reinaldo Ramos-Ramos, an illegal alien who entered the United States in June 2002 by crossing the Southwestern border, was one of 10 gang members who sexually assaulted the minor girls, ages 16 and 17, inside a vacant Adelphi, Md. apartment March 14, 2003.

The assaults might have been a savage gang initiation rite that calls for female gang prospects to either endure being "jumped in" through a beating by gang members, or be "sexed in" by multiple male gang members."

Although notable, don't think that the illegal alien crime wave is just a Mexican or Salvadorian problem. Also see:

"... A hit man had decapitated Sauzo's son, then chopped off his arms and legs. The killer was so unconcerned about being brought to justice that he scrawled his own name and nickname -- "El Barby" -- on a note left with the mutilated corpse.

Still, Sauzo's mother, Cristina Gomez, didn't bother to go to the police. "Why waste my time?" she said in an interview. "This is the way it is in a town without laws."

Gomez's reaction and the audacity of Sauzo's murder - one of 11 decapitations in the state of Guerrero this year and one of 2,000 killings in a nationwide war between rival drug cartels - are symptomatic of the unraveling of the rule of law that has plagued Mexico for years.

But in the past year, the number of spectacularly gruesome killings and the intensity of civil unrest have spiked to such alarming levels that even Mexicans who were once hardened by years of violence are shocked.

... The bulk of the violence is the result of a barbaric, five-year war between Mexican drug cartels which are now approaching the strength and size of the notorious Colombian cartels of the 1980s. Drug killings have nearly doubled in the past year; in a single incident this month, six police officers were fatally shot in the troubled state of Michoacan.

... "We have a huge problem, a problem that exists throughout the country; it's difficult, complicated, dynamic," said Juan Heriberto Salinas Alt', a retired army general who serves as Guerrero state's public security director. "It's something we've never seen before."

... In Guerrero, a southern Mexican state best known for its Acapulco resorts, drug killings have ballooned from 32 at this point last year to 281, according to Salinas Alt's, the public security director. Only a handful of those murders have been solved because of "a high level of police corruption," he said.

... Tamayo Hernendez, known as workaholic family man, was found Nov. 10 naked and dead in a cheap roadside motel room. That day, a Tijuana police chief was shot to death. A headline in the Mexico City newspaper El Universal called it "A Normal Day in the Country," and in an editorial, the paper lamented that "bit by bit, murder by murder, the country is winning an international reputation for danger."

As noted in Mexico's Drug Wars Heat Up "In the once-chic beach resort of Acapulco, the severed heads of two police officers who had been clamping down on drug traffickers were found a few months ago with a note attached: "So that you learn to respect." The grisly method soon caught on. In August alone, four more heads accompanied by threatening notes appeared in the central Mexican state of Michoacán."

Something to think about the next time you are vacationing in Mexico.

In any case, these are some of the criminal illegal aliens that are freely coming across the southern border to set up shop and operation in America. How serious is the problem? In answer to that question, you might want to check out what Congressman Tom Tancredo says about the problem as noted in a World Net Dailey report, Mexican drug cartels take over U.S. cities.

As just a quick peruse of the title of the links indicates, note the involvement in sexual crimes. I'll bet you don't see gang rape initiation rites in the Godfather movies or on the Sopranos. These are not the gangs that Elliot Ness was battling.

If income tax evasion was the only collateral damage being inflicted we could probably tolerate this aspect of illegal immigration but gang rapes?

While we passively tolerate the illegal alien invasion, this is more collateral damage of illegal immigration to save ten cents on a head of lettuce.
